Yeah, being able to delete your words before you say them is a great benefit. I wish more people followed this rule, a lot of spiteful things get said for no reason. What's the point of being rude or insulting someone? Does it make you feel better about yourself? In that case just pretend you said it and let people have their joy. Why go out of your way to make someone unhappy? Luckily for me I have the power to erase it whenever I see it. Here, at least.
